Implemented ship autonomous movement
	(The ship oscillates back and forth between screen bounds)

Instantiated Sensor class
	Need to implement method of object detection
	Potentially, a function which maps a sensors
	coordinates to a particular zone of objects,
	so as to reduce the search space and prevent
	collision testing for all existing objects.
		Alternatively, this could be reversed,
	instead dividing sensors into zones, doing one
	sweep of all objects, and checking only the
	sensors in each object's zone.
